New HT22 quick-change toolholder system from Wirtgen for maximum milling performance and cost efficient operation

Cutting technology is a core competence of Wirtgen and the heart of its cold milling machine technology. Its continuous development is always aimed at increasing the performance and cost efficiency of cold milling and offering customers reliable solutions. This also holds true for the quick-change toolholder system for point-attack cutting tools, the robust upper part of which can be quickly and easily replaced directly on the job site. With its HT22 quick-change toolholder system, Wirtgen has launched a new development onto the market that minimizes downtimes and increases the service life of the milling drum.

Longer service life, fewer downtimes

A longer service life and fewer downtimes are achieved by various optimizations, such as the significantly enlarged contact areas between the upper and lower parts. Consequently, the high cutting forces are reliably transferred to the lower part of the quick-change toolholder system, substantially increasing the useful life of the milling drum. A larger shank cross-section and the optimized shank geometry increase the strength of the shank, thus providing greater resistance to undesired deformation. Additionally, the maximum longitudinal wear of the upper part of the toolholder has been doubled in relation to that of the conventional version. And last but not least, the higher pretensioning forces resulting from an optimized screw position provide for the reliable system pretensioning of the upper part in the toolholder's lower part. Service intervals have now been extended from 250 hours to 500 hours thanks to the system's overall more robust construction.

Wirtgen cutting technology: powerful and economical

All new Wirtgen cold milling machines have been equipped with the new HT22 quick-change toolholder system since October 2013. Machines put into service earlier can easily be retrofitted with the new system, providing customers with the ideal tools for future milling jobs.
